Question

我试图在whereHas中使用whereBetween，但我的whereBetween无法正常工作，因为whereHas没有从我的用户模型获取我的转向属性：

这是我的查询

DB::raw("*, ( 
        3959 * acos( 
        cos(radians(?)) 
        * cos(radians(latitude))
        * cos(radians(longitude) - radians(?)) 
        + sin(radians(?)) 
        * sin(radians(latitude)))
    ) AS distance"))
->having('distance', '<', $distance)
->orderBy("distance")
->setBindings([$lat, $lng, $lat])
->whereHas('user', function($q) {
    $q->whereBetween('date_of_birth',array(Input::get('age_from'),Input::get('age_to')))
      ->where('gender',Input::get('gender'))
      ->where('title','LIKE','%'.Input::get('title').'%');
})
->with('user')
->get();

用户模型

<?php namespace App;

use Illuminate\Auth\Authenticatable;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Auth\Passwords\CanResetPassword;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Contracts\Auth\CanResetPassword as CanResetPasswordContract;

class User extends Model implements AuthenticatableContract, CanResetPasswordContract {

    public function getDateOfBirthAttribute()
    {
        $ca = \Carbon\Carbon::parse($this->attributes['date_of_birth']);

        return $ca->diffInYears();
    }

}

位置模型

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Location extends Model {

    protected $table = 'locations';

    public function user()
    {
        return $this->belongsTo('App\User');
    }

}

查询中的出生日期字段没有将转换后的值转换为年，而是获得日期格式的值，如表格中的YYYY-MM-DD。

Answer 1

我找到了解决方案，但没有必要从其他模型访问该属性，只需使用此whereBetween。

$q->whereBetween(DB::raw('TIMESTAMPDIFF(YEAR,users.date_of_birth,CURDATE())'),array(Input::get('age_from'),Input::get('age_to')));
